Application filed April 13, 1925. l Serial 110.22,?22.

his invention relates to new and useful improvements in deflectors t'or slip actuatinp; weights.

The object of the invention is to provide a deflector tor slip actuating weights for tubing catchers, casingspears and the like.

A particular object of the invention-is to provide a deflector held infixed relation to the lower end of a slip actuating weight for preventing unintentional upward displacement 01 the weight, due to impact or pressure resistance when lowering the device into the well.

A further object is to apply such deflector to the device without enclosing the weightsustaining spring and thereby avoiding a sand trap.

A. particular object of the invention is to support the deflector in close relation to the bottom of the weight by securing it to the tubing section of the device.

A construction designed to carry out the invention will be hereinafter described top'ether with other features of the invention.

The invention will be more readily understood from a reading of the following specilication and by reference to the accompanying drawings, in which an example of the invention is shown, and wherein 2- Fig. 1. is a partial. elevation of a tubing catcher showing the slip actuating weight and a deflector constructed in accordance with my invention,

2 is an enlarged cross-section on the line 2 2 of Fig. 1, and

Fig. 3 is an enlarged cross-sectional view on the line 33 of Fig. 1.

In the drawings the numeral 10 designates the upper tubing section or mandrel and 11 the lower tubing; section or mandrel of an ordinary tubing; catcher such as is now in common use and of the type shown in Let ters Patent No. 1218,2349, issued to S. A. Guibcrson, J12, March Stln 1917: and while I have chosen such a device with which to illustrate my invention, it is to be understood that it may e applied to any tool or device of this character or in which slip actuat ing weight is used. I have only shown a part of the tubing catcher and this is deemed suilicient to explain the invention.

It will be seen that in lowering the catcher into a well casing, an impact sustained by the lower end of the weight 11, such as a sudden contact with a body of oil or the resistance oiferedby the upward flow of a heavy gas pressure, would force the weight upwardly and raise and spread: the slip, thus causing the catcher to unintentionally grip the casing and interfere with its downward passage.

The upper and lower tubing sections 10 and 11 are united by a sleeve 12. i The slip actuating weight 13 is mounted to slide tree ly on the upper section 10 above the sleeve 12. The sleeve has an annular flange 141 at its upper end. In order to prevent unintentional or accidental displacement of the weight, I provide a deflector collar or ring 15 which is mounted snugly on the sleeve and is dished to receive the said flange. The collar 15 may be fastened on the sleeve by spot welding or in any other suitable man ner.

For normally supporting the weight immediately above the collar I employ a support or carrier comprising a flat base ring 16 having a plurality of vertical flat bars or posts 17 extending from the outer ed of the ring to the bottom of the weight. These posts pass loosely through apertures 18 in the deflector collar 15. The ring 16 rests upon a coiled compression spring 19 supported on a. coupling 20 on the lower end of the lower section 11. The deflector collar 15 is larger in diameter than the weight 13 and has its outer surface rounded transversely. By this arrangement the proximity of the lower end of the weight and the deflector collar is maintained.

It will be seen that the Weight 18 and spring 19 are free to operate without interitercnce from the deflector. The collar is set close enough to the bottom of the weight to protect the same, but sufficient space is left by the apertures 18 t0 afford a free drainup e through the collar.

Various changes in the size and shape of the different parts, as well as modifications and alterations may be made within the scope of the appended claims.

What I claim, is

1. In a fluid deflector for a slip actuating ill) weight comprising, a fixed support, a deflec- 2. In a fluid deflector for a slip actuated weight, a sleeve for mounting on a tubular conductor, an annular deflector collar fastened on the sleeve and extending outwardly therefrom, and a weight support extending longitudinally above and below the sleeve and collar and movable relatively of the sleeve and collar.

In a fluid deflector for a slip actuating wei ht comprising, a relatively fixed deflector collar, and a weight carrier sliding vertically through the collar.

4.. In a fluid deflector for a slip actuating weight comprising a relatively fixed deflector collar, and a spring sustained weight carrier sliding vertically through the collar.

5. In a fluid deflector for a slip actuating weight comprising, a relatively fixed collar having apertures, and a weight carrier comprising upright members sliding through the collar.

6. In a fluid deflector for a slip actuating weight comprising, a sleeve for mounting on an axial support, a deflector collar mounted around the sleeve and having a rounded outer surface, and a weight carrier slidable vertically oi the sleeve and collar.

7. In a fluid deflector for a slip actuating weight, the combination with an axial support and a weight slidable thereon, of an annular deflector collar fixed on the support imn'iediately under the weight and being larger in diameter than the weight, and a carrier for supporting the weight and being slidable vertically of the sleeve and through the collar.

In testimony whereof I atlix my signature.
